M fesignates operative connections betweenqthe lateral stabilizingmeans and the aviato'rs seat C.

Of all the above features recited as parts of a suggested provision of members afitl elements of a flying machine organization,"

the onlyfeatures which are concerned in the present invention are the lateral stabilizing means L, the operative connection M and the "the entire flying machine, and the member 6 is located substantially at said vertical turning axis. Each of said members a and 6 comprises a relatively fixed portion or fin 6 and arelatively movable portion 7, both of said portions 6 and 7 in each instance lying normally in a vertical fiplane, or in the same vertical'plane of the ying machine or the frame H thereof. The operative connections M include actuating means it for the relatively movable portion 7. The members a, b and 0 aredisposed between upper frame membersv 8 and 8 and the body or car D, and a lower fra me member 9, in the former frameillustrated. Each of the members a, b and 0 comprises two spaced plane portions, 10 and 11 respectively, which normally'lie in parallelism,jand comprise a common textile or other fabric covering 12, the same being maintained 1n proper rmation by a .frame consisting of aforward upright 13, I

rearward spaced uprights 14, and lower spaced bars 15. The uprights 14 are loosely spective upright 13, as at 17; but in the case of the member 6, the uprights 14 are loosely connected with the bottom of the car or body D or a bar connected therewith, and the textile fabric 12 is suitably connected with the body or saidbar. 'The outer ends of the uprights 14 and of the bars 15 are connected together, as at 18, in pairs. and each upright 14 and its bar 15 is cqnnectedwith the other upright 14 and bar 15, at Ine points of connection, by'a link 19. Each upright 14 and its connected bar 15, together with the frame member 8 or the car or body D or rod connected therewith, as the case may be, and the upright 13, constitutes a.;frame for one of the portions 14 of the respective members a, b or c; th'e fabric'12 being stretched over both frames and secured to the lower bars 15. v The portions of the frames rearwardly of a line drawn between the loose connections 16 and 17, are capable of movement relative to the remaming portions of the frames, thus constituting together with the fabric 12, the relatively movable portions 7 and 6 of the members. The actuatmg means 11. comprise a continuous shaft 20 suitably journaled upon the frame member 9 and extending through suitable o enings in the uprights 13, and being provi ed between two port1ons14 of each of the members a, b and c with a crank 21. The aviators seat C is mounted upon a rock shaft22 so as'to be capable of lateral oscillation, being normally held in horizontal position by springs 23. The operative connections M nclude a sprocket wheel 24 upon the rock shaft 22, a sprocket wheel 25 upon the shaft 20 and a link belt 26 passing around both of the sprocket wheels. v

, Normally, the cranks 21 together with the portions 7 a of the members (1,6 and c, and the portions (5 thereof, lie in vertical planes of the flying machine or frame 11, as shown in full lines in Fig. 5. When one of the aerocurves A' or B is elevated by'a disturbance of lateral stability of the flying machine, the seat'Q is inclined toward the same side, causing the operative connection M to rock the shaft 20 in such manner that the cranks 21 are thrown to the elevated side of the machine, as indicated in dotted lines in Fig. 5. The cranks 21'are enlarged progressively rearwardly of the machine, that of the member a being the smallest or having the least are of travel and that of the member 0 being the'largest or having the shaft 20. All ofthe cranks being thrown at the same time, to final degrees of anguconneeted with the frame member 8 or 8, 'as the case may be, as at 16, and the lower. bars 15 are loosely connected with the relarity, but being of di erent size and arc'of travel relatively movable portions of the members a, b and a are given progressively ening by a more or less constant variant, it

requlres less lateral deflection of the relatively movable portion 7 of the member a than of the relatively movable portion of the member I), and less lateral deflection of the relatively movable portion 7 of the memher 6 than of the'relatlvely movable portion 7 of the member a, to produce the same amount of reaction at each of said members, resultant. u'pon im ingement of the atmosphere upon the re ativel movable portions of said members, to produce equivalent stabilizing eflectthroughoutall the members.

It will be understood that the rearwardly moving air-streams, passin along the faces of the fins 6, will strike t e deflected portions 7 and tend to urge said deflected portions laterally in such manner as to restore transverse equilibrium or stability of the machine. Likewise, when the disturbance of; transverse stability is resultant upon certam lateral or transverse atmospheric disturbances, the deflection of the relatively movable portions 7 will allow the air cur rents less impeded movement at such points, releasing the members a, b and o from the excessive pressure so caused. As soon as lateral stability has been restored the seat G is restored to normal balanced position, and the entire members a, b and 0 return to flat normal condition, the cranks 21 being moved through the operative connection M -to the inert ositions, as shown in Fig. 2, andin .full lines in Fig. 5. In Fig. 3 the parts are shown in inert positions in dotted lines and in active positions in full lines Asthe members a, b and c aremounted beneath the horizontal plane of the center. of gravity, it will be understood that lateral pressure or the incidence upon the same will act to restore the machine tolateral stability, in the manner above specified.

I do not desire to be understood -as limiting myself to the specific provision, construction, combination, association and relative arrangement of parts, members and fe'atures shown and described; but reserve the right to vary the same, in adapting the improvements to varying conditions of use, without departing from the spirit of the invention and the terms of the following claims.

Having thus described my invention, I claim and desire to secure by Letters Patent:

1. A flying machine provided with lateral stabilizing means comprising a plurality of normally "plane members disposed in a series longitudinally of the machine and beneath the center of gravity thereof, each of said members comprising relatively movable portions, a movably mounted aviators seat, and operative connections between the aviators seat and said members whereby the portions of said members are relatively moved, throughout all of said members, simultaneously, and to varying degrees.

2. A flying machine provided with stabilizing means arranged longitudinally thereof and both forwardly and rearwardly of the vertical turning center of the machine; said &

stabilizing means comprising a plurality of members, and means for laterally moving the same to varying degrees.

3. A flying machine provided with stabilizing means comprising a plurality of members disposed beneath the center of gravity thereof and longitudinally thereof both forwardly and rearwardly of the vertical turning axis thereof, and means for laterally moving said members to varying degrees.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
